FAQ - Sleeve Bearings vs Ball Bearings Performance | GGB

GGB sleeve bearings offer several advantages. When choosing between sleeve bearings (also called bushings or plain bearings) and ball bearings for a given appliion, one must consider several factors, including longevity, friction, noise, temperature, mounting, lubriion issues, cost and ease of installation and replacement. Each factor may

Balls - Enduro Bearings

Ball Grade: Rounder Spins Smoother. Balls are rated by their grade. A Grade 3 ball means that the ball is 3/1,000,000” tolerance of sphericity, and so is extremely round. In fact, the races of any bearing can’t come close to this level of precision in their trueness, but every component being closer to perfect helps decrease friction.
